Eppendorf ULT Freezers are known for their energy efficiency, reliability, and worry-free, long-term sample preservation. They provide many of the same basic features as our Innova ULT Freezers and high-efficient ULT freezers. The polyurethane foam insulation (incl. vacuum insuation panels for CryoCube F740) combined with a highly efficient cooling system achieve and maintain ultra-low temperatures of -86 °C.
Expanded options for enhanced security: The following models of the CryoCube F740 series are available, you can select the best fit for your needs:
F740 with LED interface, classic cooling liquids, and air-cooling
F740i with touchscreen interface, classic cooling liquids, and air-cooling
F740iw with touchscreen interface, classic cooling liquids, and water-cooling
F740hi with touchscreen interface, green cooling liquids, and air-cooling
F740hiw with touchscreen interface, green cooling liquids, and water-cooling
The volume is 740 L (26.1 square feet). The temperature range is from -50°C to -86°C.
Need for special set-up?
All units are available as 3-compartment or 5-compartment instrument. The 3-compartment unit has 3 shelves (fixed bottom one + two removable shelves). The 5-compartment unit has 5 shelves (fixed bottom one + 4 removable shelves).
The air-cooled versions offer a left-handed or right-handed outer door handle as option to adapt the freezer to the conditions in your lab.
The built-in inverter technology enables the same freezer to be used on 100, 115, 208, and 230 V, just change the power cable.
Focusing on sustainability?
The "h" versions are the green flagships - by using hydrocarbon-based cooling liquids (R290/ R170), the power consumption is further reduced compared to non-"h" versions.
CryoCube F740 models are also validated by the ACT concept of "My Green lab".
The CryoCube F740i, F740hi, and F740hiw are certified by ENERGY STAR®.
Bothered by loud ULT freezers?
The CryoCube F740 has an improved sound level of 47.8 dB. The "i" versions provide you some silence level of down to 41.3 dB. These "i" versions are equipped with a sound-reduction-system. Based on a different air filter position at the front of the freezer, the air flow is now guided in a more silent way towards the ventilation system. At the backside of the freezer, a special compartment further reduces the sound level. Relax when working near a CryoCube F740 "i" version.
Burdened by unsorted boxes cluttering your freezer?
Make your scientific life easier: Store your freezer storage boxes within organized freezer racks. The CryoCube F740 series offers two different ways to store boxes: The 3-compartment and the 5-compartment style. The maximum of 576 boxes can be stored in a 3-compartment CryoCube F740, equipped with MAX racks.
For other racking systems, please check the inner dimensions of the freezer and contact Eppendorf.
Worried about the safety of your high value samples within your ULT freezer?
The "i" versions are equipped with a touchscreen interface where data are stored on-board and can be checked 24/7. If necessary, data as well as service reports can be extracted by a front-mounted USB port. The electronic lock system enables controlleded access and higher sample safety.
The handling concept is based on ou longterm expertise of Eppendorf PhysioCare combined with extensive user test sessions.
Support the epGreen initiative with your Eppendorf ULT freezer
Eppendorf Ultra-Low Temperature freezers are among the most energy-efficient in the industry, reducing energy consumption by thousands of kilowatt hours over our competition.
As being on of the very first movers for green gases at -86°C, Eppendorf has now 10 years of experience in R&D, production, logistics, and service in the field.
Factors influencing the energy consumption
- Thickness of insulation
- Type of insulation
- Type of cooling liquid
- Efficiency of compressors
- Control of compressor
- Pressure in cooling system
- Style of cooling loops (diameter, length, density,..)
- Sealings of outer door
- Sealings of inner doors
- Insulation of inner doors
- Insulatioon of outer door
Our part for sustainability
- Production moved into new building with state-of-the-art building insulation to save heating energy and power
- Heat output during final individual unit testing discharges building heating system
- Plastic and cardboard compactors introduced + waste rebate system in place
- Local requirements for waste management (collection of electronic waste like circuit boards, recycling via authorized recycling organizations) and internal guide lines
- Usage of green cooling liquids in Eppendorf ULT freezers for 10 years
- Packaging parts have increasing share of recycled origin
- Packaging is more than 99% recycable (wood, cardboard, PE-foil)
- REACH + RoHS compliant
- Marketing material is printed on FSC certified paper, wherever possible focus on pdf only
- Shipment by cargo ship to reduce CO2 footprint
